Thanks for your help re the benzene question. All of my lotions are made in a lab and have preservatives. I make my own anhydrous body butters and I am told that it doesn’t need preservatives but I am wondering if I should use something anyway if I am going to sell these products. I use antioxidants like vitamin c and elderberry oil. I know that these aren’t preservatives. Because people take out the body butter with their fingers, even though it is made with just oils and butters, should a preservative be added? I don’t want to cause any harm to anyone and of course I don’t want to get sued.
